Spartina patens - Schoenoplectus pungens Coastal Marsh Alliance
Reference:
NatureServe Biotics 2019
Description:
Dominant herbs in Texas examples of this dune swale and low dune alliance can include <i>Fimbristylis caroliniana, Fimbristylis castanea, Hydrocotyle bonariensis, Panicum virgatum</i>, and <i>Spartina patens</i>. Other species typically include <i>Andropogon glomeratus, Andropogon virginicus, Centella erecta, Eleocharis</i> spp., <i>Eragrostis</i> sp., <i>Juncus</i> sp., <i>Paspalum monostachyum, Phyla nodiflora, Pluchea foetida, Rhynchospora colorata, Rhynchospora</i> spp., <i>Samolus ebracteatus</i>, and <i>Schoenoplectus pungens</i>. In one Florida association, <i>Sporobolus virginicus</i> is usually the most common species, with patches of <i>Iva imbricata, Paspalum distichum, Sesuvium portulacastrum</i>, and <i>Spartina patens</i>. In Louisiana, on the Chandeleurs and related islands, <i>Spartina patens</i> replaces <i>Uniola paniculata</i> (which is present only in small amounts) as the dominant grass along the upper beach and primary dune. This alliance is found in the maritime coastal plains from Texas and Louisiana east through Florida and Alabama to (possibly) South Carolina and Georgia. It may also occur in Mexico. This vegetation is found in seasonally and periodically flooded to saturated interdune swales and depressions on barrier islands, as well as from low flats and overwash areas and low dunes.
